The problem for me would be that i have absolutely no idea on how one could build that laptop. I wouldn't know how to build a transistor, i have almost 0 knowledge of electronics, people at that time probably knew more than i do. So, except letting them tearing the computer apart to examine it, there's not much i could do.
That's something i've always been bothered with : suppose that you'd be teleported,naked, to ancient greece, how could you prove to them that you come from the future ( provided language isn't an issue). In my case, the only thing i could came up with were maybe some basic notion of how the human body works, biologically. But that's very thin.
I know a bit about general relativity, quantum mechanic, physics, logic, etc. But i'm in now way sufficiently advanced in any of those subjects to prove or demonstrate anything to anyone.
Don't worry about it most complex circuits these days are in chips so not even electrical engineers know much about how to build one.
Unless you build chips for a living it's very unlikely you could build anything to the level of a laptop from today not to mention you need to build the lab/clean room to manufacture the chips.
Technically if you know how the chip worked you could reproduce it with 1975 tech but it would be as large as hell.
The best thing you could do is guide their research in the right direction since you already know the way and you could get them there quicker.
I'm an EE and can confirm this. An EE who does something other than microelectronics can generally understand how those circuits work, but is generally unable to design a non-trivial one.
I was thinking you'd be able to MacGyver solutions for common problems if you went back to that time, although then I found out that in Greece (or Rome, wherever) they had steam engines that opened gates and the like, so they were more advanced than was commonly thought. (I forgot the name, but the steam engine was a copper ball with exhausts on two sides; boil water in the ball, steam comes out the exhausts and causes a turning motion)
Prove the principles. Built a n-bit marble binary adder. Then prove you can encode state using electric potential, they had glass at the time, so one creative soul can setup uber-large jar transistors. Enjoy your newfound god status.
